I suppose I should have mentioned that I downloaded these photos from the MIT
physics lab photo gallery. Sure is a nice looking rotary. Much nicer than
the one I built and have never used yet. I have a very large photo
collection of Tesla coils, spark gaps and capacitors that I have downloaded
from many different places. You know the saying, a picture is worth a 1000
works.
